Bloke: Doctor, I've got this terrible pain in my arse
Doctor: Drop your trousers and bend over. Hmm, it looks like you've got a lettuce leaf protruding from your sphincter. I'll pull it out. And there's another. And another.
Bloke: ARGHGHGHGH! The pain is excrutiating! Is there much more?
Doctor: I'm sorry to tell you, but this is just the tip of the iceberg.
